Isn't Liquid's 1.9x series GB based? Those eat the ROM space *and* your RAM hardcore. To save on battery, you'll need to either undervolt / downclock your CPU (which makes GB drag its heels on the DROID), or else go back to a FroYo-based ROM.

 

I am currently working on a smooth as butter ICS ROM. If you are interested in testing for me I can send you links to it.. of course you would have to update frequently, but mostly everything works (enough works for the rom to become a daily driver) it's over clocked, does not consume all your RAM, VERY customizable (CM9 Based) and extremely stable. PM me for more info!
